This report should be reassigned to package udev or if a subject change is necessary be closed(?). I will then issue a new report to udev. The bug (regression) can be fixed in the file /lib/udev/rules.d/50-udev-default.rules. The (block) devices /dev/fd[0-9] shall be (as before) in the group floppy as a write-permission is necessary to spin the drive down. I reported the bug to the udev-package (#775 144). The behaviou was decleared as designed and the bug report closed. I added the missing line to /etc/udev/rules.d/91-permissions.local.rules to keep it permanent, and that should fix this bug permanently. -- Bjarni I.

SUBSYSTEM==block, GROUP=disk SUBSYSTEM==block, KERNEL==sr[0-9]*, GROUP=cdrom Adding SUBSYSTEM==block, KERNEL==fd[0-9]*, GROUP=floppy created the floppy device with the right group. -- Bjarni I.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 reassign 765426 linux thanks This wouldn't have anything to do with mount or util-linux since it is the kernel that controls the ancient and long obsolete floppy disk drive. It also seems rather unlikely that it would have a bug at this point and troubleshooting such a thing is extremely difficult ( even if someone capable still has a floppy drive, which they stopped putting in computers about 10 years ago ) so this is likely going to never be resolved and chalked up as broken hardware, but I'll leave that up to the kernel guys.

Put a floppy into the drive, mounted, changed to the mounted directory, read some files, and unmounted the floppy. * What was the outcome of this action? Floppy directory was unmounted, but the light for the drive was still on and there was still a slight humming, indicating that the floppy was still rotating.

Floppy light would go out, humming stop and it would be all right to manually eject the floppy. -- System Information: Debian Release: jessie/sid APT prefers testing-updates APT policy: (500, 'testing-updates'), (500, 'testing-proposed-updates'), (500, 'stable-updates'), (500, 'proposed-updates'), (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: i386 (i586) Kernel: Linux 3.2.60-rt87-2 Locale: LANG=is_IS, LC_CTYPE=is_IS (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Versions of packages mount depends on: ii libc6 2.19-11 ii libmount1 2.25.1-3 ii libselinux12.3-2 ii libsmartcols1 2.25.1-3 mount recommends no packages.
